Acquisition in 2009) was firstly presented and used in public manuscripts, This term describes in fact a multiple relationship between the target write value of the SSD and the actual write value, and the smaller the write amplification value, the more the solid life can be improved.To fully understand the write amplification, we need to understand the SSD's read-write mechanism first. We know that the SSD

How to optimize SSD solid-state drive in Win8 system
One, AHCI hard disk mode can improve hard disk performance, determine your solid state drive is running in AHCI mode, specific can be installed in the motherboard BIOS in front of the system set up!
Second, turn on the TRIM function to reduce disk wipe operation, extend the flash life of solid state hard disk, Windows 8 by default, the trim instruction is open, if you want to query the
Solid-State hard disk storage medium is divided into two types, one is the use of flash memory (Flash chip) as a storage medium, the other is the use of DRAM as a storage medium.
Solid-state hard disk based on flash memory
Flash-based solid-state drives (IDE flash disk, serial ATA flash disk): Flash chips are used as storage media, which is what we usually call SSDs. Its appearance can be made into a variety of shapes, such as: Notebook hard disk, micro-hard disk, memory card, USB flash driv

With the price of SSD solid-state hard drives down, later assembled computers to use SSD solid-state hard drive will become mainstream, at present, SSD solid-state hard disk capacity is small, and the price than mechanical hard drive to have no advantage, compared to ordinary mechanical hard drive, the gap between the big price. Believe that the
SSD solid-state drives know that if the SSD partitions do not have 4K alignment, the performance will be a discount. But maybe someone with the same encounter this situation, clearly zoning when the choice of 4K alignment, but after the system with as SSD benchmark this tool after detection is extremely depressed, why C disk will show not 4K alignment?

compared with the desktop, we have a relatively low demand for notebook performance, so in the process of upgrading the notebook hard drive is the pursuit of performance or large capacity, or both? Small series will come up with three solutions to discuss with you.
For the different needs of the user groups, we will be the notebook upgrade program roughly summed up in the following three kinds:

This article is for reading book next Generation Databases:nosql, Newsql, and Big Data Chapter 7th: The End of Disk? SSD and In-memory databases notes.The disk is dead?Bill Gates said in 1981:
640K of memory should is enough for anybody.
In 2001, he realized that the previous statement was wrong:

: This article mainly introduces how to install lubuntuubuntu to optimize tmpfs, which causes startup failure of apache2nginx. if you are interested in PHP tutorials, please refer to it. When SSD is optimized,/var/log is placed in the ramdisk of tmpfs. restart causes the apache2 and nginx directories in/var/log to be lost, and apache2/nginx cannot be started.
Solution: in ~ /. Create these two directories in ~ /. Add at the end of bashrc. (Oh, use
The biggest difference between SSD and HDD is that it does not have the necessary mechanical parts of the HDD, the disc, the head rocker arm, which is determined by the different working principle of two kinds of hard drives. SSDs save time in mechanical parts movement compared to HDDs, and the primary storage element NAND flash used by SSDs is an electronic component, so its data travels much faster than HDD.In addition, according to the test, the HD

The company's ERP system has a large amount of data, with 40 GB of data and 90 + concurrent users and 1000 + connections. The original IO performance cannot meet users' operation response requirements, and report query is slow, all the indexes have been done, and the index is re-built once a week, but the problem still cannot be solved. To this end, the company purchased the dell poweredge R720xd server, which supports two arrays and 24 hard disks, dual-CPU, 64 GB memory, more awesome. We have c

How to adjust the boot sequence of SSD after installing solid state hard disk in computer
1, after the computer restart, point del into the motherboard interface, go to boot, you can see the start of the sequence of display;
2, the problem is not seen in the startup preferences of solid-state drives, and then enter hard disk Drive BBS priorities;
3, in the choice of the inside can see solid state hard drive and mechanical hard dri
To the introduction of solid-state drives, compared to the old mechanical hard drive, SSD solid state hard disk is said to be the same as the rocket speed, the installation of solid state hard drive after the Win7 system, whether the boot or operation has a quality upgrade, but many friends may not know, the use of solid-state drives there are some need to know the optimization methods, Allows your solid-state drives to perform optimally in Win7 syste
